The Federal Aviation Administration early Wednesday ordered airlines to
pause all domestic departures until 9 a.m. ET, to allow the agency to restore a critical system that alerts pilots and crew to safety advisories and other information for flights.
The agency, which oversees and manages the aviation network in the U.S., said it is working to restore its so-called Notice to Air Missions System. “Operations across the National Airspace System are affected,” the FAA press office said. It said it was performing final checks to get the system back up and running.
Reportedly some international flights to London and Tokyo were still taking off.
